Turn your computer into an audiophile-grade music source

Computers are great sources for music except for one glaring problem: they don't sound very good. That's where a high-quality digital-to-analog converter, or DAC, will help by transforming your digital audio files into sweet-sounding music. Sony's UDA-1 does just that, with all kinds of formats, including high-resolution DSD and FLAC files. Better yet, it's also an integrated amplifier, so it can power your speakers and accept other sources like CD players, an iPod® or other portable device, and even a turntable with a preamp. The UDA-1's small footprint makes it a great fit for a high-performance desktop system alongside your computer and bookshelf speakers.

Handles DSD and other high-res formats

There are lots DACs out there capable of decoding high-resolution files in formats like FLAC and AIFF. But the UDA-1 also offers full support for Direct Stream Digital, or DSD, a Sony-developed format first used in Super Audio CD. These high-resolution files offer sound that, for many listeners, is closer to analog than digital has ever come. With more record labels, including Sony Music, rolling out DSD downloads, this DAC offers the versatility to enjoy this exciting format as well as many others.

Make all your digital tunes shine

Besides DSD, the UDA-1 handles the most popular digital audio formats, from MP3s to CD-quality lossless and high-res files. The Digital Sound Enhancement Engine helps make even low bitrate files sound their best by digitally restoring high frequencies that are lost in file compression. So whether you're playing old MP3s downloaded from iTunes® or high-res downloads from sites like HDtracks, the UDA-1 will deliver them with rich detail and smoothness.

It's also an integrated amp

The UDA-1 makes a great standalone DAC as part of a hi-fi stereo system. But if you're setting up a desktop system with your computer, connect a pair of bookshelf speakers and let the UDA-1 also serve as an integrated amp. The dual-mono circuit layout minimizes interference between the left and right channels for faithful reproduction of your music. And the rigid chassis with aluminum top and front panels prevents vibration-induced distortion from creeping into playback. Need more power? You can use the UDA-1 as a preamp and connect it to a power amplifier to drive more demanding speakers.

Everything you always wanted in a stereo receiver, except the radio

An integrated amplifier is essentially a receiver without a built-in AM/FM tuner. You get power to drive your speakers, audio controls, and inputs for music source components. Connect an iPod, a computer, a network music player, or any other device that can play Internet radio, and you may find you have no need for an AM/FM radio.

Features

High Quality Construction: The Sony UDA-1 USB DAC Amplifier features
solid aluminum (3mm thick) construction. The UDA-1 employs an acoustically tuned, custom block capacitor and
concentrates all its audio signal paths into a single ground point to eliminate
fluctuation of left- and right-channels, and contributes to dynamic sound.

Digital Sound Enhancement Engine (DSEE): When turned on, the DSEE
offers natural sound with a spacious feel by restoring high frequency sound and
the tail shape of the waveform that likely disappears during the audio
compression process.

Analog FIR Filters: This digital-to-analog converter effectively
reduces high-frequency noise in DSD signals. It features independent right and
left channels, with four analog FIR (Finite Impulse Response) filters per
channel producing a combined one-clock delay. FIR filters are ideal for D/A
conversion of DSD signals.

USB (type-B) Port For Computer Audio: The Sony UDA-1 features an
asynchronous USB (type-B) port which can be used to connect the USB DAC
Amplifier to a free USB (type-A) port on your Windows or Mac computer for
music playback. You'll be able to use any music player like iTunes, Windows
Media player, Media Go, or Sony's
Hi-Res Audio Player
software to enjoy high-resolution music stored on your computer. Your computer
must meet the following system requirements:

Sony's Hi-Res Audio Player: Sony's
Hi-Res Audio Player
(for Windows or Mac) is player software that allows you to play back
high-quality audio files stored on your computer through the UDA-1. You can
play back high-resolution audio files, such as DSD files, purchased in music
distribution websites, simply by connecting the USB DAC amplifier to your
computer via USB. You'll be able to create, save, and edit playlists, and play
your favorite music in any order.

Front-Panel USB Port (Apple & Sony Compatible): You can connect
select Sony or Apple devices to the USB (type-A) port on the front-panel of the USB
DAC
Amplifier using the USB cable that came with your mobile device and enjoy music
playback from that device through the UDA-1's connected speakers or headphones.
The UDA-1 will also charge your Sony or Apple device while connected.
You will continue to navigate your music and view song/artist information from
your mobile device. Compatible devices include (as of 1/22/2014):

Note: The front-panel USB port does not support USB thumbdrives,
computers, HDDs or other Android and Apple devices not listed.

Digital Inputs: The Sony UDA-1 is also equipped with one optical
(toslink) and one coaxial (RCA) digital input for connection of a CD player,
SACD player, DVD player, or Blu-ray player. The digital inputs only support 2ch
PCM and do not decode 5.1ch (Dolby Digital/DTS).

Analog Inputs & Outputs: The USB DAC Amplifier features a stereo
analog RCA input to connect an external analog audio source. A stereo analog RCA output
lets you use the UDA-1 as an external DAC for your your home stereo system.

Two-Channel Class AB Amplifier: This analog 20W x 2Ch (in
4ohm) Class AB amplifier
utilizes an EBT (emitter balance transistor) with a cutoff frequency of over
300MHz for the final transistor. The amp device features minimal phase variation
up to the high range and excellent transient response. Its twin mono format with
separate left and right channels eliminates left-right sound interference and
ensures clear, high-quality sound reproduction. The resilient high range
reproduces sound with rich musicality and a high degree of faithfulness.

Binding Post Speaker Terminals: The USB DAC Amplifier is equipped with
a set of binding post speaker terminals to connect a pair of loudspeakers. The
binding post speaker terminals will accept bare wire (up to 12-gauge), banana
plugs (single/dual), or pin-connectors. The amplifier can accept 4-ohm to 16-ohm
speakers.

Note: Switch the unit's rear-panel Equalizer switch to "Bypass" when you
use speakers other than Sony's SSHA3 speakers (sold separately).

Headphone Output: When headphones are plugged into the full-size 1/4"
jack on the front-panel, the speaker outputs are automatically muted.

Remote Control: The UDA-1 comes with an IR remote for wireless operation of
the USB DAC Amplifier's input and audio controls. You will continue to navigate
your music from your computer or mobile device.

Auto Standby: If you switch the Auto Standby switch on the rear-panel
of the USB DAC Amplifier to "ON", when you are not using the USB DAC Amplifier
or there is no digital signal input to the UDA-1 for 20 minutes, the unit will
automatically turn off and enter standby mode to reduce the power consumption.

Protection Circuit: When an abnormal current is output to the speaker
terminals, or when the internal temperature of the USB DAC Amplifier is too
high, all the input indicator lamps flash for 5 seconds, and the UDA-1 turns off
automatically.
